If you can't hear properly, please raise both your computer volume and video volume to 100% since I was total shit at video editing at the time of the video being posted.
Another way to speed up your computer is to use the program "Disk Cleanup". To access it, just go to Start Menu, "Computer", then right click on your Local Disk and click Properties. In the lower right hand corner, you will see Disk Cleanup. Click it and then wait for it to run. (It will take up to a couple minutes to 30 depending on how fast your computer is.) When it is finished, be sure to check the boxes of everything you want to delete and then click "Cleanup".
